These two muscles are synergists or "yoke muscles" as both attempt to move the eye over to the left or right. The condition is commonly unilateral but can also occur bilaterally. [2] The unilateral abducens nerve palsy is the most common of the isolated ocular motor nerve palsies. [3]
There are several options of treatment when iatrogenic (i.e., caused by the surgeon) spinal accessory nerve damage is noted during surgery. For example, during a functional neck dissection that injures the spinal accessory nerve, injury prompts the surgeon to cautiously preserve branches of C2, C3, and C4 spinal nerves that provide supplemental innervation to the trapezius muscle.

Rare cases involve abducens nerve paralysis affects lateral eye movement while trochlear nerve paralysis affects vertical eye movement. [11] Similar to headache, ophthalmoplegia usually resolve gradually and completely over time, but recovery may be incomplete after several episodes. [11]
Damage to the abducens nucleus does not produce an isolated sixth nerve palsy, but rather a horizontal gaze palsy that affects both eyes simultaneously. The abducens nucleus contains two types of cells: motor neurons that control the lateral rectus muscle on the same side, and interneurons that cross the midline and connect to the contralateral ...
The oculomotor nerve controls all the muscles that move the eye except for the lateral rectus and superior oblique muscles. It also serves to constrict the pupil and open the eyelid. The onset of a diabetic third nerve palsy is usually abrupt, beginning with frontal or pain around the eye and then double vision. All the oculomotor muscles ...
Treatment includes a healthy diet, salt restriction, and exercise. [2] The medication acetazolamide may also be used along with the above measures. [2] A small percentage of people may require surgery to relieve the pressure. [2] About 2 per 100,000 people are newly affected per year. [4] The condition most commonly affects women aged 20–50. [2]
The study, which involved 106 peri- and postmenopausal women and was presented at the Endocrine Society’s annual meeting in May, indicates women should self-monitor their vasomotor symptoms and ...
The abducens nerve is most likely to show signs of damage first, with the most common complaints retro-orbital pain and the involvement of cranial nerves III, IV, V1, and VI without other neurological signs or symptoms.
